Sectors are pie-shaped regions on a hard disk that store data. Which of the following parts of a hard disk do not contribute in determining the addresses of data?

The correct answer is B. Interface. Data addressing on a hard disk uses the CHS (Cylinder-Head-Sector) scheme or LBA (Logical Block Addressing). The physical address of any data block is determined by the cylinder number, the head number, and the sector number. The interface (SATA, PATA, SCSI, NVMe, etc.) is…

Explanation

Data addressing on a hard disk uses the CHS (Cylinder-Head-Sector) scheme or LBA (Logical Block Addressing). The physical address of any data block is determined by the cylinder number, the head number, and the sector number. The interface (SATA, PATA, SCSI, NVMe, etc.) is simply the electrical/logical connector between the drive and the system - it handles data transfer but plays no role in determining where data is physically located on the disk.
